Paul: I gave away my years of Sing out years ago but - if I remember correctly, the Evatones included were not full songs. They were just excerpts so you could hear what the tuning was. There's be a dozen songs on each one. This is different than when SO begain including CDs with full recordings to those who were supporting subscribers (I was) And as for Nat Geo. There were two issues with Evatones (to my knowledge). The Space one and one with Winston Churchill's speeches. I have both of those. And then there was the issue of the adult mag "High Society" with an aural version of oral ,ovemaking. These pop up on Ebay a lot! Steve In a message dated 4/20/2015 10:58:02 P.M.

They never stayed flat either, since the magazine inevitably got folded by the Postal Service. And the expense nearly bankrupted the magazine, but board member (and regular columnist) Pete Seeger had threatened to resign if they didn't include the discs, so that readers who didn't read music could learn the songs.
